To alt whom ii- -may conm-n:

Be it, known that T. ALPRBD G. Bn'cmrz. a citizen of the United States, residing at' San Jaeinto, in the county ol' Riverside :ind State OI t'zdifornio. hnv'e im'ented new :ind useinl Imprm'ements in 'l'ires, of which the following is u s wciti ntion.

This inrention relntcs to improvements in tires for :intoniobile :ind other Vehicle Wheels, :18 hereinniicr described :ind cluimed.

One object ei the inventinn is to ell'ect improvements in the construction of tne heel run.

A further ohject is to eil'ect. improvements in the construction of the. cushioning tire.

ln the nccompnnying druwing, Figure. 1 is nn ehfivntion ol :1. whecl proridi d with my improved riin :ind tire. hig. 2 is :1 detaxil trnnsverse sectionad view through the tire :ind riin. Fig. 3 is ;i detflil longitndinzd sect-ionnl view et' the same.

ln accordance with this 'Inventio the wheel rim l is formed with 2] tixed or integrni thingo 2 nt one. side. :ind with u detuclmble thmge ut the opposite side, the said thinges bein prm ided with inwurdly extending bosses 4 of which :my suitnhte number may be employed :ind which mzry be ,21.1 :my suit- :xble distance. apart. The benring or outer thee 5 of the riin which't'orms the bottom of the. peripherzd minntur circumh-.rent inl groove ol' the rim between the tlnnges 2, 3 thereot. is inclined l-.iternlly in one direction ns shown in Fig. 2.

The tire 6 which is tl eushioning tire made of ruhber, eonlposition, or other suitfible elustie orresilient. nmterinl, is provided with u il'ZllbYl'lSPiy rounded head or trend portion 7 :ind with z] nurrowed inner portion S which is ndnpied to tit in the groove of the rim fo] med between the ibmges or walls :2, 3, und to bent' against. the treud fae-e 5 ol' the riin which' forms the button. of said groove. The head being brzmder then the inner portion S ef the. tire forms luternl or side shoulders or Overhnngs t) which bear upon the outer edges of the walls orihinges :2, 3, such outer edges ol' such walls or ilunges being outwnrdly rounded on their inner sides, :is shown, und the said overhnngs or shoidders 9 being concuved Or hollowed in their under or inner sides, :is :it 10, to adapt them to receive and tit on .sm-h rounded edges of such walls or flunges. The bosses of sin-h wnlts or ilnnges bl'l'tilll pressed into the sides of the nurrowedi Specification of Letters Patent.

l inner portion of the t-ire so that when the detechnble thingo or well 3 isin place and the suid nerrowed inner ortion of the tire is chnnped between suc detaehable Wall or tlzmge and the t'Lxed integral Wall or thingo 2 ef the. Wheel rim, such hosses become. embedded in the side suriaees of the said tire and the letter is prevented from erawling". In the inner side of the tire nre openings or 'g recesses 11 which :tre nbstuntinlly ovoidul in g form mid which serve to lighten the tire, ef-

fect nn economy of the material of which the tire is formed :ind also serve to t'orm loczilized eushions in the. tire which ndd to the resilieney und the elustieity thereoi. The said :itely spili-cd upnrt. l he nnrrowed inner 5 port ion ol' the tire is :dso provided with transverse opening:: in which tubuhir sleeves 12 l ere placed which url tni sniteble length end dimneter :ind which ben r between the. thinges or side ':dls '2, I, of the riln. Bolts 13 extend through :dining openings in such walls i or tlnnges '3, and dso through such tubuler l sleeves, their heads prnereidy beating I egninst'the deteehnble wnli or Jlunge 3. lt, fwill be understood that. the sziid holts and t sleeves eozu'twith the side walls or ilanges ioi the rim to securely and yet detnehebly g insten the tire on the riin. By first removi ing the nnts iroin the bolts and then remov- I ing the detzichuble wadl or thingo 3, the tire l nmy be rendily drown from the said bolts and i detnched from the wheei rini. A reint'orcing i spring ring 15 is enihedded in the tire nt e i point beyond the outer ends of the :nr cushg lens, :is shown in Pigs. '2 und 3. lt. will be. ohserved upon reference to Fig. i 3 of the drewings thet the reint'orcing ring which is clnbedded in the t-ire is spztced from und lies without the air eushions formed by t the recesses 11. This arrangement of the re.- i inioreing ring with reference to the air uns-h ions Causes the ring to prevent crzu'ks which mey originnte nenr the cushions from extendi ing to the ontersurince ot' the tire.

llnving thus described the invention, what I ehzini :is new and desire 'to secure hy Letters Petent ist- 1. A Vehicle wheel having :i rini provided with eripherzil thmges one of which is 1'e-. move le, in combination with n eushioning tire having reees'ses in its inner side ferming loenlized eir eushions therein and bolts con- -necting such fiunges together, extending openings, recesses or ehumbeis are uppropri thmug .such tire and also extending through In tcstimony whereof, affix my signature certain Of such localized air cushions; in resence of LWO witnesses.
